The Soft/FX uses a different approach to handle the reduction of sharpness and resolution of an image. This is done by distributing many oval lenses of different intensities in the laminated glass. The resulting image is affected in a slightly different way from that obtained by acid etching of a digital diffusion filter.

Due to the size at which the internal lens can be produced, the light that is deflected on these internal lenses is deflected on an overall effect of the image. Consequently, the softness is more widely distributed across the image, which means that the resolution is reduced to a higher degree at a lower density. The physical effect of this process also means that the diffusion of light deflected by the lenses in the higher densities produces a slight halo around practical and specular light sources.
